Growth and technical change in Korean agriculure

Description

The principal task facing the Korean economy is to further increase
total farm output to meet the requirements for farm products.
This study attempts to find economic means of carrying out a
further increase in the total farm output.
In order to carry out this work, this study attempts to survey
the sources of the past growth in total farm output with reference to
the measurement of technical change and factor input-output relationships
based on the aggregate production function.
An...[Show more] attempt is made to formulate five aggregate production function
models involving various factor inputs, and to provide empirical estimates
of their paramenters. The various factor inputs are measured as land,
labour and other input.
In particular, an attempt is made to estimate the magnitude of
unbiased technical change and to establish the role of technical change
as a source of the growth in total farm output. The quality of land is
measured through the relative proportions of upland and paddy field and
irrigated land input; and also the quality of labour input through the
schooling level of farm labour forces. These quality adjustments of land
and labour input are used in an attempt to explain apparent technical change.
From the empirical results estimated by the aggregate production
function models, it is evident that an unexplained residual or output
augmenting technical change remains as an important source of the past
growth in total farm output, though apparent technical change occurs
through the effects of education on labour input and through the
improvement in the irrigated land input.
